Definition of limit temperatures of the proposed subdivision scale for operating temperature ranges of energy storage systems , , , . Analogously, sensible thermal energy storage in the high temperature range can be called high temperature sensible thermal energy storage or HTS-TES.
Options of capacity expansion for sensible thermal energy storages. In addition to increasing the volume and thus also the mass, which is also common for other types of storage, if thermal load limits of other components are neglected, the upper (operating) temperature and thus the temperature range can be increased for S-TES.
One of the main challenges for latent thermal energy storages is the phase change itself which requires a separation of the storage medium and HTF. Furthermore, PCMs usually have a low thermal conductivity, which limits the heat transfer and power of the storage.
In high-temperature TES, energy is stored at temperatures ranging from 100°C to above 500°C. High-temperature technologies can be used for short- or long-term storage, similar to low-temperature technologies, and they can also be categorised as sensible, latent and thermochemical storage of heat and cooling (Table 6.4).
On the basis of the previous project, some characteristics like the geometry and the storage material were optimized. The volumetric capacity of the storage material will be about 550 Wh/ (m 3 K) and is supposed to be able to reach up to 1200 °C. It should be mentioned that these are direct electrically (internally) charged concepts.
The latter two concepts have their high values, due to their significant higher indicated density of the used storage material of almost 4000 kg/m 3 and even more than 5000 kg/m 3, respectively. This raises the energy density potential significantly, as the other storages are in the range of 2000–3000 kg/m 3.
